How does Original Medicare work?
You don't automatically get Medicare when you become eligible. You must sign up.
You can enroll in Medicare during the Initial Enrollment Period (IEP) that begins three months before the month you turn 65 and ends three months after the month you turn 65. Most people will be automatically enrolled in Part A, but there are certain situations where you may need to manually enroll in Medicare Part A and/or Part B during your IEP. In order to avoid paying late fees, it is important that you sign up before you turn 65. This applies if you retire at age 65 or if you are enrolled in a Covered California plan.
If you’re enrolled in a Covered California plan, you could save almost $1,250 per month in plan premiums by switching to a Blue Shield Medicare Advantage Plan. That’s nearly $15,000 per year.*
If you have health insurance through your employer or your spouse's employer, look at your options before signing up for Part B. Please note that Part B has a monthly premium. Ask your benefits administrator or human resources representative for help in choosing the right option for you. Or call Blue Shield of California at (855) 203-3874. We’re here to help.
Enrolling in Medicare beyond the Initial Enrollment Period
- You might be charged a penalty fee for failing to enroll during your Initial Enrollment Period
- If you did not enroll during the IEP when you were first eligible, you may enroll during the General Enrollment Period
- The General Enrollment Period for Original Medicare (Medicare Parts A and B) occurs each year from January 1 through March 31
- When you turn 65, you may choose to forgo Medicare Part B when you become eligible. You will be able to enroll when your group coverage ends.
- Your eight-month SEP for Medicare Part B begins either the month that your employment ends or immediately when your group health coverage ends.
- If you enroll during an SEP, you do not have to pay a late enrollment penalty.
